Abstract
Description
Technical Field
[0001] This invention relates to the field of optical lens inspection technology, specifically a high-resolution miniature OLED observation eyepiece. Background Technology
[0002] An eyepiece is a visual optical device used to observe the image formed by the optical system in front. It is a component of visual optical instruments such as telescopes and microscopes. Its main function is to magnify the real image obtained by the objective lens again. In order to eliminate aberrations, an eyepiece is usually composed of several lenses and has a large field of view and viewing angle magnification. Currently, the resolution of many eyepieces is generally low. Utility Model Content
